On profinite properties of knots and 3-manifolds.

Michel Boileau (Aix-Marseille Université)

Monday 25th January, 2016 16:00-17:00 Maths 522


The profinite completion of a group is a way to encode all finite quotients of the group. In this talk we will discuss profinite completions of 3-manifold groups and the relationships with some 3-manifold properties or invariants, like the Thurston norm and fiberness. In particular, we will be concerned by the case of knot complements in the 3-sphere. This is a joint work with Stefan Friedl.
